Abstract

The invention provides a cleaning and maintenance device which is mounted in ink jet printing equipment. The cleaning and maintenance device comprises an ink scraping device used for scraping ink on a spray nozzle of the ink jet printing equipment; and the ink scraping device comprises a scraper, a cutter holder and a cutter rack, wherein the scraper and the cutter holder are fixedly connected and the cutter holder and the cutter rack are detachably connected. The invention further provides the ink jet printing equipment which comprises the cleaning and maintenance device. The invention provides convenience in assembly and disassembly of the scraper and shortens manual maintenance time of the jet head maintenance device.

Description

technical field [0001] The invention relates to the printing field, in particular to a cleaning and maintenance device and an inkjet printing device. Background technique [0002] The solution of piezoelectric inkjet technology is to place many tiny piezoelectric ceramics near the nozzle of the print head. By applying the image information voltage to the piezoelectric ceramics, the piezoelectric ceramics will expand and vibrate and deform, and the ink in the ink head will be uniform and accurate. squirt. Piezoelectric inkjet technology can control the volume of ink droplets within a small range. At the same time, piezoelectric inkjet nozzles are more likely to be blocked by foreign matter, which affects normal inkjet printing. After the ink heads of piezoelectric inkjet printing equipment become clogged, a lot of time has to be wasted cleaning the nozzles. [0003] figure 1 An inkjet printing device is shown, including: a printing host part 1 , a spray head 2 and a cleani...
